In carrying out the invention, there is provided an improved cake decorating and finishing machine including a hollow supporting base orhousing generally designated by the referencenumeral I having a bottom 2 and a top 3 separated by a vertical cylindrical side wall 4.

A small electric motor 5 is secured to the bottom 2 and is adapted to be operated by means of any suitable source of electric current supply (not shown) connected therewith by means of the usual electrical conductors 5. The motor 5 is provided with an elongated shaft 6 upon which the worm 1 is secured, the outer end of said shaft being rotatably mounted in a bearing 8 supported in the bracket 9 secured to the bottom 2.

A vertical bearing Ill is attached to the bottom '2, and an aligned depending vertical bearing II is welded at I2 to the metal top 3 for rotatably supporting the vertical drive shaft I3. A gear i4 is secured tothe shaft I3 and meshes with the worm 'I being driven thereby.

'I'he shaft I3 extends upwardly through the top 3, and through a vertical bearing collar I5 .which terminates at its lower end With-the enlarged disk shaped weight I6 which is welded thereto at-| 1.

A plurality of upwardly extending T-shape brackets I8 are Welded at I9 to the top 3, being arranged at apart, and support the overflow receptacle 20 which is U-shape in cross section, being welded at 2| to the upper ends of said brackets I8..

The upper end of the drive shaft I3 is reduced as at 22, extending a short distance above the vertical bearing collar I5, and supports the washer 23 and the bearing collar 24 spaced apar by the split ring 2'5. I

The bearing collar 24 is formed with radially extending supporting ribs or arms 26 which are secured at their outer .ends to an upstanding band or ring 21. A piece of wire mesh fabric 28 is disposed over the band or ring 21, and a larger clamping band or ring 29 is slipped over the band or ring 21 and the edge of the wire mesh fabric 28 to clamp the same tight in position, thus forming the cake supporting turntable generally denoted by the reference numeral 30. The upper reduced end 22 of the drive shaft I3 extends through the wire mesh fabric 28 and a slight distance above the same.

A cardboard cake supporting disk 3| will be` A vertically apertured clamping collar will l be supported upon the vertical bearing collar l5, and will be provided with a set screw 36 for locking the collar 35 in the desired adjustment.

A transverse bore 31 will be formed through the collar 35 for supporting the laterally extending rod or arm 38 which will be adjustably mounted therein and secured by means of the set screw 39.

A clamping collar 40 will be threaded upon the outer end of the rod or arm 38, and will be vertically bored to receive the vertical rod or arm 4|, being held in the desired adjusted position by means of the set screw 42.

A clamping collar 43 similar to the clamping collar 40 will be disposed upon the upper end of the rod or arm 4|, and will be provided with a set screw 44 for locking the same in the desired adjusted position.

, A- transverse inwardly extending rod 45 will be attached to the clamping collar 43 at one end and will support the clamping collar 46 at its inner end. The collar 46 will be vertically bored and provided with a set screw 41 for supporting various types of icing devices, one of which is represented by the reference numeral 48, and each having a supporting stem 49 receivable in the bore in the collar 46.

A collar 50 will be disposed upon the rod or arm 4| being held in the desired adjusted position by means of the set screw 5| and a bore to receive the shank 52 of a cake side icing implement 53.

A collar 54 is adapted to be supported upon the vertical rod or arm 4| and held by the set screw 55. A forked supporting member 56 is adapted to be held by the collar 54 extending inwardly in spaced relation of the cake 33.

An icing reservoir and dispensing receptacle 51 is provided, being of substantially rectangular shape in cross section. A cover 58 is hinged at 59 to the receptacle 51, and a slidable bottom 60 is disposed in the lower end of said receptacle for dispensing the icing invlarge quantities when desired.

A depending angularly disposed discharge spout 6| is positioned at the lower end of the receptacle 51, and is provided with a cut off lvalve 62.

A follower 62' of triangular shape in cross section is disposed in the icing receptacle 51 for vertical movement, being provided with a metal guide strip 63 secured to its upper surface and 4formed with upstanding bearing flanges 64 on its opposite sides engageable with the inner wall of said receptacle 51, serving as bearings for the follower 62 as it moves upwardly and downwardly within the receptacle 51.

An upstanding pin or peg 65 will be supported upon the strip 63 for supporting the several centrally apertured weights 66 for causing the follower 62 to follow downwardly in the receptacle 51 upon the icing when placed therein for discharging the same upon the cake 33 when the control valves are opened.

A pair of oppositely extending horizontal bearing collars 61 and 68 are secured at the bottom of the receptacle 51 for positioning upon the parallel spaced arms of the forked supporting member 56.

If desired, a special icing or cream dispensing tube 69 will be used, the same comprising concentrically arranged barrels 1B and 1| with alignable ports 12 and 13, and with a supporting stem 14 receivable in the clamp 46 on the inner end of the rod 45. A ilexible tube 14 will connect the inner end of the dispensing tube 69 with a suitable receptacle (not shown) for containing a supply of icing or cream. A knurled operating head 15 will be formed on the inner barrel 10 for rotating the same to align or disalign the discharge ports 12 and 13.

From the foregoing description, the mode of operation of the improved cake decorator and nishingmachine will be as follows: A disk 3| will be placed upon the wire mesh fabric 28 upon the rotatable turntable 30 and a cake 33 to be iced will be disposed upon the disk 3| with the upstanding teeth or prongs 32 embedded in the bottom of said cake. The disk 3| will be centered upon the turntable 30 due to the placing of the same with its central opening 34 over the reduced upper end 22 of the drive shaft |3.

The icing receiving and dispensing receptacle 51 will be filled with the desired amount of icing of a particular color and consistency, and will be supported upon the forked arms 56 above the cake 33 with the discharge spout 6| disposed adjacent the edge of the cake and overlying the same. If it is desired to decorate the upper surface of the cake the icing will be discharged on the top of the cake and the implement 48 will be supported in the clamp collar 46 and the icing will be permitted to flow upon the top surface of the cake while the cake is being rotated with the turntable by means of the electric motor 5. The implement 48 will engage the icing and will be manipulated in such a manner that the icing will be spread as desired over the upper surface of the cake. The implement 53, as clearly illustrated in Figures 2 and 13 will be disposed in position to engage the side of the cake as the icing flows from the icing receptacle 51 down the sides of the cake 33 so that the cake will be thoroughly iced as it is rotated upon its supporting turntable.

The icing or cream dispensing tube 69 may be substituted for the implements 48 and 53, and by manipulating the knurled head 15, the bores 12 and 13 may be brought into alignment to per mit the icing or cream to flow therethrough from the suitable source of supply (not shown), and the tube 65 may be manipulated over the cake to produce the desired decoration or design required. Obviously the icing or cream may be colored as desired, so that when a particular type or decorated cake is desired, a photograph or replica of the same may be placed in front of the cake maker and decorator to follow.

It will also be obvious that the several supporting arms and the implements for icing the cake may be adjusted as desired so that any particular design of cake may be quickly and eciently produced.

It will be apparent that the surplus icing or cream which will flow down the side of the cake 33 being iced will pass through the wire mesh fabric 28 and collect in the overflow receptacle 20, where it may be removed and used for icing other cakes.

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in detail of construction may be resorted to Without departure from the spiritvof the invention.
